ミシガンに限って，ということになるかも知れませんが．．．
女性は特に身体症状と不安が増えるそうです．またたばこ，アルコールの習慣については変化なしと．

Results
Most participants reported increased caloric intake, weight gain, and less exercise. They also reported increased time with family. More women than men reported physical symptoms and anxiety related to stress. Smoking and alcohol intake were essentially unchanged. No associations were identified between length of residence in the US and health lifestyle habits or other health outcomes.

Conclusions
Negative lifestyle changes occur in diet and exercise for overseas Japanese people, but a positive change in increased family time was found. Women appear to be at a greater risk for somatic disorders than men. As duration of stay does not appear predictive of adverse changes, clinicians should advise patients going abroad of these risks regardless of the term of the work assignment.

滞在期間との関係はないそうです．

これは，利益相反やPublication biasに繋がらないだろうか．．
